This study investigated the preventive effect of 5-aminolevulinic acid combined with sodium ferrous citrate (5-ALA/SFC) on blood-aqueous barrier (BAB) breakdown induced after anterior chamber paracentesis (ACP) in beagles. 5-ALA/SFC (1/0.64 mg/kg or 3/1.

The metabolism of 5-aminolevulinic acid (ALA) is more efficient when combined with sodium ferrous citrate (SFC). Our previous study revealed that oral administration of ALA, which has anti-inflammatory properties, and SFC (ALA/SFC) immediately before lipopolysaccharide (LPS) inoculation suppressed endotoxin-induced uveitis (EIU) in rats. However, the therapeutic effect of ALA/SFC post-administration remains unexplored.

Article Synopsis
  • Sodium ferrous citrate (SFC) enhances the anti-inflammatory effects of 5-aminolevulinic acid (5-ALA), which is significant in reducing inflammation in a rat model of endotoxin-induced uveitis (EIU).
  • The study found that administering 5-ALA/SFC improved ocular inflammation, as evidenced by reduced clinical scores, inflammatory cell counts, and cytokine levels, similar to higher doses of 5-ALA alone.
  • Mechanistically, 5-ALA/SFC was shown to inhibit key inflammatory pathways, including NF-κB activation, while also promoting protective pathways involving HO-1 and Nrf2.

This study aimed to investigate the anti-inflammatory effect of 5-aminolevulinic acid (5-ALA) on endotoxin-induced uveitis (EIU) in rats. EIU was induced in male Sprague Dawley rats by the subcutaneous injection of lipopolysaccharide (LPS). During LPS injection, 5-ALA diluted with saline was administered via gastric gavage.

Systemic capillary leak syndrome is a rare and life-threatening disorder, characterized by recurrent episodes of unexplained hypotension, hemoconcentration, and hypoalbuminemia. This condition is caused by leakage of plasma and proteins into the extravascular space and can be classified as either idiopathic or secondary. Secondary systemic capillary leak syndrome can result from cancer, infections, medications, or surgery.

This study aimed to compare the in vitro and in vivo retention, bacterial adhesion, and biofilm formation between anionic and zwitterionic bandage contact lenses (BCLs) in healthy canines. BCL retention and tolerance were evaluated in 10 healthy canines via a single-masked, crossover study for 7 days. To compare in vitro bacterial adhesion and biofilm formation, four strains were incubated with the BCLs at 37 °C for 2 or 24 h, and the bacterial colony forming units (CFUs) adhering to the BCLs were counted.

Background: The Smith-Waterman algorithm is known to be a more sensitive approach than heuristic algorithms for local sequence alignment algorithms. Despite its sensitivity, a greater time complexity associated with the Smith-Waterman algorithm prevents its application to the all-pairs comparisons of base sequences, which aids in the construction of accurate phylogenetic trees. The aim of this study is to achieve greater acceleration using the Smith-Waterman algorithm (by realizing interpair block pruning and band optimization) compared with that achieved using a previous method that performs intrapair block pruning on graphics processing units (GPUs).
